I am very much in the “cables don’t change sound unless they are broken.” While I still abide by this, this cable has made significant improvements in sound. I have an iPhone X and a Cayin RU7 DAC. I got a certified lightening to usb-c cable on Amazon. The audio would drop all the time, opening apps would cut out, moving the phone too much even caused issues and halt playback. I got another certified cable and same results. This cable has completely resolved the issue. The previous cables also don’t seem to have provided enough power because the bass response is massively improved as well.
Yeah it’s expensive, but just get it. The build quality is insane as well. And it doesn’t get as hot.
A lightning connect cable did not accompany my Cayin RU-7 purchase, and I was warned that this DAC pulls a lot of power from the iPhone and the wrong cable can stutter the power from the phone to the DAC. This ddHiFi cable works great and build quality is good. I don’t have another cable to compare the sound, but I’m getting great sound to my IEMs and absolute silence when nothing is playing.
